such as will enable others skilled in the art large chamber 1n the shell for a carrying charge A, which is red by thev to which it appertains to make and use the same. a

. This invention relates to rockets, and par- .remain to injure persons or property in the fall.

I have heretofore been granted Letters Patent of the United States No. 957210, for the destruction of the shell and for causin the guide rod or stick to fall in a horizonta manner, but as there is still danger from the falling stick, and from the base of the shell which is not always destroyed, I have invented the further means for rendering the 'de rod and all parts of the shell harmess, as new and useful, improvements over my former patent, as more fully explained herein. v

I have illustrated my invention by the accompanying drawings:

F1 re 1 represents a longitudinal sectiona view of the. shell with a portion of the guide rod in place. 7

Flgure 2 represents a cross section of the shell taken on line 2 of Fig. 1.

Figure 3 represents a view similar to 2 with parts removed,

Figure 4 represents the guide rod and explosive tube contained therein.

Like numerals on the difierent figures represent like parts. 1, is the ordinary rocket shell, with my 'de rod 2afiixed, 3.is the acking the ordinary, uick match fuse 4, which extends up throug tube 5 to give a large area for burning of'the carrymg charge to form easily press gases which are driven out from the mouth of the tube in the abutment 6, all as usual.

Abovethe chamber 3 I .have aflixed two partltions, 7 and 8, which may be of clay or other suitable material which is readily shattered by a sharp hard explosion, the space between these partitions forms a chamber 9 in which I place a detonating charge 0 or suitable explosive for destroying.t e partitions and shell and firingmy other destroying agent as hereinafter shown.

The charge in 9 is ignited through the duct 10 when t e carrying charge has burned up to that point.

Above chamber 9 is a larger chamber 11 in which is placed any suitable display materials such as parachute 11 or stars, flags or signals, etc. The walls 12 of this chamber are thin, and are readily burst by a light explosive B carried in the chamber beneath the display articles. A light cap 13 covers the chamber and display articles and is read- 11y blown oil by the charge B. The pointed cap. 14 over all facilitates the u ward passage. The charge B is ignited y a quick match or fuse 15 which extends from chamber 11 through the wall thereof and down the outside 0 the shell to a point below the part1t1on and there enters the chamber 3, and is igmted b the carrying charge when 1t burns up to t e lower end of the fuse 15. The lower end of, 15 is so spaced below 7, that the charge B in chamber 11 will have been exploded and the articles of display dispersed before the fire reaches and explodes the charge in the chamber 9.

For my guide rod, 1 use either a tube wh1ch may be formed of card board .or other suitable material, or preferabl a wooden stick shown as 2, which may the shell b a bracket number 16, with a sloping en 17, into which the corresponding sloping oint 18 of the rod 2 may be until sufliciently ti ht to remain in position to guide the mo et. This bracket may be rovided with flanges 16 afiixedto the shel 1. In the outer side 0 the rod adjoining the shell'is cut a deep groove 19, wherein is carried my destroying agent in thin tube 20. A hole 21 is pro vided through the wall of the chamber 9 near the top end of the" rod 2, through which the end of the tube 20 is inserted until it is embedded in the detonating'explosive C.

In tube 201 use a quick acting explosive 23, which is not exploded by the necessary manipulations and transportation, but which is readily explodedby' the blast of a detonating explosive such as contained in the charm her 9, and I preferably use the cordu Bickford tube, or one containing such explosive known as T. N. T. in leadfoil or thin lead tubing, which can be readily bent to enable the point to be inserted into the hole 21 till embedded in the charge in 9.

Where a-tube is used for the guide red, the tube may be carried within the tubular rod, and where the grooved stick is used. The tube 20 may be held within the groove by glue or other suitable means. In cases where it is desired to facilitate packing for transportation, the sticks and shells may be disconnected, as shown in Figures 3 and4 and tube 20 may be rolled on suitable spools and shi ped separately.

I'pre erably place the fuse 15 on the side of the shell opposite the hole 21, and affix a suitable wrapper 22 around that part, or all, of the shell, which 'wrapper holds in place and protects the fuse 15, and also closes the mouth of the hole 21 and prevents the explosive inchamber 9 from escaping. This covering is readily punctured by the end of the tube 20' when it is pressed into place as shown in Fig. 1. v

In the chamber 11 I have shown a simple form of parachute 11 folded and connected to a slow burning lantern, all packed about with suitable material, and supported by the light charge of explosive B, which is merely sufficient to disperse the contents of the chamber and i 1te thelantei'n, which serves as the basket or the parachute, as 11".

In operation, the rocket is fired by igniting the fuse 4 and the carrying charge in chamber 3, and when the rocket is near the end of its upward journey the light charge B, in chamber 11 is ignited by the fuse 15, and shortly after the articles in such chamber have been thereby dispersed, the detonating char e C in the chamber 9 will be ignited an the blast therefrom will cause the bursting charge, a cover for sea a loud report and bright flash and the partitions and walls of the shell be torn to small fragments thereby, and by the same blast of the detonating char e, the contents of tube 20 will be expl ed throughout the length of the rod, and all parts of the rod be torn to small particles. The action of the explosive in tube 20 being practicall instantaneous, any parts of the shell whic remain other than minute after the blast from chamber 9, will be further reduced by the blast of the tube 20, and all danger from falling parts of the discharged rocket thereby removed.

Having described my invention I claim:

'1. A rocket comprising a shell body having a plurality of chambers therein, a propelling charge in one chamber a dispersin charge in another, and a destroying an detonating charge in another chamber, said last named chamber being arranged between the said first named chambers, a quick burning fuse connecting the dispersing chazfie with the propelling charge to be fired b latter at a point below the floor of-the detonating chamber, said propelling chamber and detonating chamber having an opening therebetween, and a guide stick adjustable to the shell and provided with a tube of explosive material extending alon the length thereof and connected with t e detonating chamber.

2. A pyrotechnic rocket comprisin a shell having a carrying charge and a urstin charge therein, said shell being provided with a hole through the side thereof 01) tilsige o e and a guide for the shell, said guide having a flexible tube filled with an explosive carried thereby, said tube having one end bent to perforate the cover and contact with the bursting charge, said guide and said tube being adjustably connected to the said shell.

In testimony whereof I aifix my signature.
